Summer is coming soon, my project will help those who complain about the heat. This homemade fan is made to cool down objects. This fan can be used by anyone.  I am using my own creativity adding on to some inspirations on the internet to create this magnet powered fan. It is powered by a battery, using the strength of 2 magnets. When the fan is activated, it will transfer it’s electrical energy to kinetic energy. This is because the fan needs electric energy to spin, and then when it spins, kinetic energy is formed. Therefore this project is focused on a device that transfers electrical energy to kinetic energy. I can create my project on a stable platform so it will be portable and convenient to bring around. I will paint the base with different colors to make it more aesthetically pleasing. The existing products for precedents are fans and air conditioning.


For this product, I have to consider the safety, usefulness, and efficiency.
